SSDs versus spinning-rust drives

[David Schwartz]

$100 for a 5GB drive? WTF?

I sure hope that’s a typo…

As someone else pointed out, SSDs are running about $100 / TB. 

I’d think you’d have to be almost insane to buy a 10TB SSD. Dell has a 7.68TB SSD for $25k. Intel has an 8TB SSD for $2k. Micron has a 7.68TB SSD for about $800. Samsung has 4TB SSDs for $500.

Unless you’re working on large video files and you’ve got a mega-powerful machine with 65GB of high-speed RAM, I can’t really see the value of a really huge SSD like that for primary storage.

Spinning HDDs are a lot cheaper. You can get an 8TB Seagate backup drive for $130 or so. That’s what I’m using for my backups right now, and it’s fine. 

The USB 3.1 V2 interfaces on regular HDDs are pretty damn fast, but nowhere near as fast as SSDs. And my experience is they’re very sensitive to heat, and slow way down when they’re under constant use for very long (eg., 100GB+ files).
